A bone loss of 1.5 mm during the first year of loading has been acceptable according to the early standards. However, more bone stability can be expected with the development in implant designs and surfaces over the past decades.\n\nAim of the study: the aim of this study is to radiographically assess the crestal bone changes following delayed implant placement in mandibular previously augmented posterior sites, comparing cases with equicrestal implant placement with subcrestal implant placement",[28,29],"Implant Therapy","Augmentation, Alveolar Ridge",[31,32,33,34,35],"crestal bone level changes","subcrestal implant position","crestal implant position","augmented ridge","dental implants","RECRUITING","2026-01-26",{"date":39,"type":40},"2026-01-27","ACTUAL",{"date":42,"type":40},"2025-01-01",{"date":44,"type":22},"2026-12-01",{"name":46,"class":47},"Misr International University","OTHER",1,{"id":50,"slug":51,"hasResults":11,"nctId":52,"briefTitle":53,"officialTitle":53,"acronym":4,"eligibilityCriteria":54,"healthyVolunteers":11,"sex":17,"minAge":55,"maxAge":4,"enrollmentInfo":56,"targetDuration":4,"studyType":23,"phases":58,"briefSummary":59,"conditions":60,"keywords":4,"overallStatus":61,"whyStopped":4,"lastUpdateSubmitDate":62,"lastUpdatePostDateStruct":63,"startDateStruct":65,"completionDateStruct":67,"leadSponsor":69,"locationsCount":4},"100584455","evaluation-of-the-bone-volume-in-horizontal-atrophic-ridges-augmentation-using-tenting-grafting-technique-versus-khoury-technique-in-mandibular-molar-and-premolar-region-randomized-clinical-trial-100584455","NCT06889558","Evaluation of the Bone Volume in Horizontal Atrophic Ridges Augmentation Using Tenting Grafting Technique Versus Khoury Technique in Mandibular Molar and Premolar Region: Randomized Clinical Trial","Inclusion Criteria:\n\n* Age ≥ 18 years.\n* Both sexes.\n* Cooperative and likely to maintain good dental health.\n* Adequate bone height for placement of implants with a minimum length of 10 mm.\n* Totally or partially edentulous alveolar ridges.\n* Placement Patients with insufficient bone for an implant.\n\nExclusion criteria:\n\n* Presence of any local or systemic factors that might contraindicate oral surgery.\n* Poor oral hygiene.
